sounds wicked gimli, can't see an attached image though?
i'm a musician so hopefully i don't have anything big on the night before, otherwise - looking forward to it!
my seeds for the season should've arrived by then and my early sow should've germinated too so i'll have plenty to bring along myself
edit: just saw the photo further up the thread woops

it sounds like you have a problem with a number of things attacking your babies - remember first that weak/unhappy plants find it hard to defend themselves against pests, so make sure you've got them as comfortable as you can get them before you resort to using a chemical that will just as easily kill bees & other friendly creatures in your garden
you can also use bait plants to distract caterpillars, use companion planting to steer away predators, and caps of beer to kill slugs & snails
if you must use the baythroid: start low and increase as necessary, follow the bottle's instructions leaning towards using less than they recommend, and maybe be aware that trichocereus stomata are open at night and not during the day (not sure if that'd make any difference to the plant/critters but worth noting)
fungus gnats can be controlled with diatomaceous earth from what i've heard, but if you have them in your mature trichos' soil i would recommend transplanting them into a more free draining mix with a a good layer of inorganic material around the base of the stem - if you're growing things indoors, fly paper has also worked wonders for me in fungus gnat control
good luck!

from what i understand there are cytokinins in coconut water which are a plant growth hormone.
worth saying that you can't buy unpasteurized coconut water (or even coconuts) in australia, if you have a tree you're fine though of course.
apparently pasteurization makes them far less suitable for application to plants.
fb groups all rave about crushed aloe sp. mixed with water for pup induction too, not to mention human urine and urea as glaukus said above.

this study hypothesizes that bees can literally see and may also be attracted to harmala alkaloids, with plants using them as pollination signals
also contains some interesting testing on abundance & variety of harmala type alkaloids within a variety of plants - anybody got some Thalictrum aquilegiifolium seeds?
edit: i might put some p. harmala seed out in the garden and see if the bees find it interesting at all hahaha

Facial recognition software is now in use in the Perth CBD which gives me concerns about profiling, privacy, and general freedoms.
It all seems a bit bleak/dystopic, but it is important to remember there will also be people who will create new technologies for good, and ensure new/other technologies are used for good.
Hopefully for the greater population these good people are enough.
I can certainly see this sort of thing becoming an important political issue over the next few elections.
Though, I will say i had hoped that by now most people were a little less worried about negative gearing than they were about climate, artificial intelligence & the possibility of encroachment on political/social freedoms.

"Finally, someone did the smart thing and decided to use DNA testing, as well as morphology to reclassify cacti genera and species, creating the most reliable taxonomy so far proposed. This was done by the French naturalist Joël Lodé who released his findings in the publication, Taxonomy of the Cactaceae volumes 1 &2, which is the most comprehensive work on cacti ever attempted. Thankfully, he has restored the Trichocereus genus to its rightful place as being distinct from Echinopsis. His new classifications for the Trichocereus genus, including the previously accepted names is as follows~" - Brett Lothian, Tricho Serious Ethnobotany

Joel Lode classifies T. pachanoi and T. peruvianus as subspecies of T. macrogonus which answers and raises some questions.
Not sure why this writing is yellow, probably something to do with me copying & pasting the above quote.
